Unlockable Grudge Match Fighters

Perform the following actions below to unlock the fighters for the Grudge Match. However, to unlock several fighters you need to obtain illegal parts. In order to gain access to these parts, you have to have received the Majel Set, the Dark Commander Mark, and you must have beaten your doppelganger in battle. Once that’s all done, you’ll be able to access the Underground to purchase your illegal parts. To get to the proper area of the Underground, head forward from the entrance and enter the door. Now, head to the right and go straight again. You’ll come across the illegal parts shop.

Unlocking the underground

Once you beat around a dozen different grudge matches (the exact number varies), go in front of the clubhouse and fight your shadow self. Defeating him will net you some illegal parts and the dark commander mark. Talk to the suspicious man in the bottom left house in the bayside area to open the secret passage to the underground.
